A long coaxial cable consists of an inner cylindrical conductor with radius aa and an outer coaxial cylinder with inner radius bb and outer radius cc. The outer cylinder is mounted on insulating supports and has no net charge. The inner cylinder has a uniform positive charge per unit length λλ.

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

answer: i think it is (1,-2)

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
